摘  要:
1982—1983年间对湖北神农架林区关门河中的似鮈进行生物学调查。依据鳞片上环纹的切割现象鉴定年龄。体长-鳞长关系为L=2.515s—3.210.体长-体重关系为W=0.0000123L3.0396。用Voa.Bertalanffy生长方程描述该鱼生长过程,各生长参数为:L_∞=238,W_∞=219.6,K=0.258,t_0=-0.805,拐点年龄ti=3.48,拐点体重Wi=65.0。似鮈为杂食性鱼类。其食物主要为水生昆虫幼虫。第一次性成熟年龄为3龄。绝对繁殖力5.17—36.65(平均15.66)千粒,相对繁殖力112—368(平均212)粒/克体重。绝对繁殖力与体重。体长、年龄的关系为:R=0.1784L-14.585,R=0.2004W+2.728,R=4.2703t-0.011。

摘  要:
The paper deals with some results of the biological survey on pseudogobio vaillanti vaillanii (sauvage)collected from Guanmenho, a tributary of upper Hankiang,mount Sennongjia.The age of the fish is determined according to the number of annual rings characterized by the intersections oceuring between new and old group of circuli on the scale. The relationship between body length (L, in mm.) and body weight (W, in g.) can be expressed by the equation W=0.0000123 L~(3.0396). The growth of the fish is as the Von Bertalanffy's growth equation the growth parameters are: L∞=238, W∞=219.6,K=0.258, t_0=-0.805. The coordinate of the inflexion point is at t_1=3.45, W_1=65.0, corresponding to 0.296W∞.The fish is an omnivorous fish, the diet consists mainly of aquatic insect lavra. The first maturity of the fish occurs in 3 years of age. The absolute fecundify (×1000)varies from 5.17 to 36.35 (15.66 on the average); the relative fecundify ranges from112 to 368 (212 on the average )per gram body weight.The relationships of the absolute fecundify to total weight (W), standard length (L)and age (t)of the fish are expressed separately as: R=0.1784L-14.585, R=0.2004W+2.728, R=4.2703t-0.011.
